Filed Ian. 16, 1963, Ser. No. 251,932 6 Claims. (Cl. 229-14) This invention relates to containers and more particularly to an improved carton and liner assembly, the method of manufacturing the improved assembly and the method of opening of setting up the manufactured assembly.

As is well known in the art, it is often desirable to line shipping cartons or the like with a liner of material for protecting the contents thereof. The present invention is directed to particular classes of carton and liner assemblies often referred to in the art as one-piece die cut folders and full telescope containers, and is particularly directed to such assemblies having improved structural characteristics that enable the assemblies to be quickly and economically manufactured and setup.

It is therefore one of the objects of the present invention to provide improved cartons of the type characterized by a one-piece bottom and referred to as one-piece die cut folders and full telescope containers, as distinguished from cartons with the bottoms thereof formed by a plurality of flaps, which may be quickly and economically provided with a foldable or collapsible liner during the manufacture thereof. A related object concerns the method of manufacturing and setting up such a carton and liner assembly.

Another object of the invention is to provide an improved carton and liner assembly of the above-described type which may be easily and quickly set up with a minimum of handling.

Further objects, features and advantages of this invention will become apparent from a consideration of the following description, the appended claims and the accompanying drawing, in which: v

FIGURE 8 is a view in perspective of the filled carton and liner assembly of this invention after it has been closed and sealed;

FIGURE 9 is a developed plan view of a modified form of a carton and liner assembly embodying the principles of the present invention; and

FIGURE 10 is a perspective view of the modified form of the assembly in a partially setup position, almost ready to be filled.

Referring more particularly to the drawings, there is shown in FIGURES 1 through 8 a carton it of the type having a one-piece bottom, often referred to as a onepiece die-cut folder, and having a liner 12 formed of a suitable collapsible or foldable material, such as polyethylene.

Carton 10 is representatively illustrated as being fabricated from an integral corrugated cardboardblank including a bottom panel 14, side panels '16 andlS'extending from opposite sides thereof, and .endpanels 20 and 22 extending from opposite ends thereof, as best illustrated in FIGURE 1; Sidepanels 16 and 18 have fold lines 24 and 26, respectively, directed-longitudinally therer of to form topfiaps 27' and 28,re spectively, on'the ends thereof, eachfiap having a Width suflicient to extend half the Width of bottom panel 14. End panels 20 and 22 each have a fold line '30 adjacent the end' thereof to form tuck portions 32 adapted to be inserted under top flaps 27 and 28 when the assembly is eventually closed.

The carton portion of the assembly, best shown in FIG- URE 1, further includes a median fold line 34 directed longitudinally of bottom panel .14 and transversely of end panels 2% and 22, as well as fold lines 36 and 38 parallel to median fold line 34jbetween side panels 16 and 18, respectively, and the bottom panel 14. Additionally, the

cartonrincludes fold lines 39 between'end panels 20 and 22, respectively, and bottom panel'14. It is to be understood that the term side, end," top, and bottom 'are used herein to facilitate description of the assembled carton and are not to be construed as limiting either the shape or position which the carton might assume.

In accordance with certain principles.ofthe present invention, the carton blank illustrated in FIGURE 1 is adapted to be quickly and easily-preassembled with the liner 12 of collapsible material in the manner illu strated in FIGURES 1 through 3. In the preferred embodiment liner 12 is in the form of a simple pleated bagcomprising,

- in the collapsed flat state, a pair of opposite flat sides 4t) I or 18, as .best seen in FIGURE 2.

and 42 and a pair of pleated sides 43 and 44 having virtically disposed fold lines 45 and 46, respectively, formed therein. The bag is preferably of a width corresponding substantially to the length of one of the side panels 16 Sides 43 and Marc preferably of a width corresponding substantially to the width of the carton end panels 20 and 22 so that when the carton is set up liner 12 will be coextensive insize with the interior thereof. The bottom end of the liner bag is closed by a seam 50, formed by heat sealing orthe like, so that when the bag is opened it will have a gusseted bottom.

The first step in the improved method of manufacture of the above-described unique carton and liner assembly is to apply a suitable adhesive 52 to side panels 16. and 18, as best illustrated in FIGURE 1. The collapsed liner is then placed over one of the side panels of the carton blank with the bottom end 50 of the liner aligned with FIGURE 2.

median fold line 34 of the blank, as best illustrated in The. cart-on blank is then folded along median fold line 34 and the sides thereof compressed will adhere to the flat sides of the liner, in the manner illustrated in FIGURE 3.

One of l e advantages of folding the carton blank 14 along the median fold line thereof is that it provides for an alignment of the side panels which is maintained during the set-ting up of the carbon. In additiombecause of the symmetry of the blank about this fold line, the side panels end up with their adhesive covered surfaces facing each other so that a single clamping or compressing operation is sufficient to join both of the side panels to the liner. The unique structure of the improved carton and liner assembly, in particular the longitudinally directed median fold line 34 in the bottom panel, also enables the liner to be quickly and accurately positioned with respect to the carton blank in such a way that when the carton is set up the liner will have a flat gusseted bottom which accurately fills the contour of the carton. Large numbers of assemblies such as that illustrated in FIGURE 3 can therefore be quickly and inexpensively manufactured by the improved method set forth above and then stored one on top of the other in a compact manner, with the carton and liner portions of the assembly integrated in a fashion which enables the assembly to be set up quickly and economically whenever desired.

In accordance with certain other of the principles of the present invention the improved carton and liner assembly shown in FIGURE 3 may be opened or set up by an extremely simple operation or method.

This improved method comprises the steps of standing the flat assembly on the edge thereof defined by fold line 34, and then moving side panels 16 and 18 of the carton apart, as best shown in FIGURE 4, to a final position wherein they are parallel and spaced a distance equal to the width of bottom panel 14. As can be visualized, this may be accomplished by simply pushing the assembly downwardly on edge 34. Since the sides of the liner are adhered to the side panels they are in turn moved apart to thereby cause pleated sides 42 and 43 of the liner to expand to form the end walls of the liner, as well. as to form triangular gussets or reinforcing sections (not shown) at opposite ends of the bottom of the liner. The next step includes folding end panels 20 and 22 upwardly along fold lines 39 to define an open and set up carton and liner, as shown in FIGURE 5. The upper edge of the liner may then be turned over the upper edges of top flaps 27 and 28 in the manner illustrated in FIGURE 6 so that the liner will be held in a fully opened condition, to facilitate filling.

The liner is then filled and the open end thereof closed using suitable fastening means, such as tape, wire, string, heat sealing or the like. Following this, tuck portions 32 are turned inwardly of the container and top flaps 26 and 28 are then folded inwardly along fold lines 24 and 26 to fully close the container or carton. A closure tape 54 may then be applied to flaps 27 and 28 in the manner shown in FIGURE 8 to seal the container.

In FIGURES 9 and 10 the present invention is embodied in a carton and liner assembly for forming a full telescope type of container. As can be seen, the carton blank, indicated at 56, comprises a bottom panel 58, a pair of side panels 60 and 62, and a pair of end panels 64 and 66, all integrally connected to the bottom panel along a fold line 68. In addition, there is provided a median fold line 70 directed longitudinally of bottom panel 58 and end panels 64 and 66. Also, each of the side panels 60 and 62 has a flap portion 72 on each side thereof.

'Io fabricate the assembly a suitable adhesive 74 is applied to the inside surface of each side panel and a collapsed liner, indicated at 76, identical to the previously described liner, is positioned over one of the side panels with the bottom seam of the liner aligned with fold line 70, in the manner shown in FIGURE 9. The blank is then folded about fold line 70 and the two side panels pressed together to adhere them to the sides of the liner, this technique being the same as that used on the previouslydescribed embodiment.

In accordance with the above set forth improved method of setting up a carton and liner assembly, the assembly illustrated in FIGURES 9 and 10 is set up by merely moving side panels 60 and 62 apart a distance equal to the width of the bottom panel 58, which will also cause the liner to open. Flap portions 72 are then folded inwardly and end panels 64 and 66 are folded upwardly along the fold lines 68 into the position illustrated in FIGURE 10, whereupon each end panel is secured to the pair of adjacent flaps 72 by suitable fastening means, such as staples, glue, or the like. The top edge of the liner may then be turned over the upper edges of the side and end panels of the open container to facilitate easy filling, in the same manner as the previous embodiment. After being filled the container may be closed using a top tray of conventional construction.

The details of construction of the bag-like liner and the manner in which it forms a gusseted fiat-bottomed liner have not-been described in detail herein since they are described in great detail in my aforesaid earlier application.

Thus, there are disclosed in the above description and in the drawings several exemplary embodiments of the invention which fully and effectively accomplish the objects thereof.
